This is my version of a cheap and diy arduino motor shield. It is very simple and rugged. Credit goes to Ascas for the design.

Step 2: Schematic

This is the schematic and again credit to Ascas. Pin out for the motor driver is also given

Step 3: Step 1

You will start off by cutting your vero board to the arduino size. Sand down the sides for a neat finish. Start off by soldering the female headers, the L298 and the block connectors as shown

Step 4: Step 2

Next step is to solder the male headers below the female ones to make it a shield type thing. You could buy the arduino headers to make the project prettier and more sturdy but i found them to be expensive. The best way is to insert the male header in the arduino I/O pins and align the shield on top of it. Use tape to secure it and then solder away.

Step 5: Step 3

Next is to make the power and other connections along with adding the diodes. Follow the schematic and add the two resistors as well.

Step 6: Step 4

Next is to add the led and resistors along with it. Here one option is to add a LM7805 so that you could power the arduino with the the power only to the shield but for my application i didnt need that so i went with separate power supply. I also made connections to the arduino PWM pins.

Step 8: Conclusion

I used this shield to make LINUS my line following robot which i will upload soon and it worked great. I put it through endurance and it stood up to the challenge although a good heat sink is essential. Thank you for viewing and i hope i effectively communicated my build.

Th schematic is very simple but still if you have issues, double check your connections. Using a multimeter always helps :P
